HENRY W. FSHER, F BRIDGEPORT, CONNECTICUT,

COMBINED GREASE AND OIL GUN.

1l,3ll9,523.

To all whom '25 may concern.' e y Be it known that I, HENRY W. F IsHER,a

citizen of the United States, and resident of formi Bridgeport, in thecounty of F airfield and State of Connecticut, have invented certain newand useful Improvements in Combined Grease and Oil Guns, of which thefollowing is a specification.

y invention relates to improvements in combined grease and oil guns suchas are employed vor oiling and greasing lautomobile transmissions,bearings and other operative parts.

The purpose of the invention is to improve upon implements or the abovecharacter and particularly to improve upon grease 'guns of the typeshown in my prior Patent #1,165,083, by providinga gun, the nozzle ofwhich may be adjusted at an angle with respect to the barrel of the gunso that the gun may be more conveniently and safely handled in .oilingcertain parts of a machine. Further to provide an improved constructionwhereby the grease chamber of the gun may be conveniently and quicklyopened and closed for the purpose of illing the gun with grease.

With these and'other objects in view the invention resides and consistsin the construction and novel combination and arrangement ot partshereinafter more fully described, illustrated Lin the accompanyingdrawings, and pointed out in the claims .hereto appended, it beingunderstood that various changes in the form, proportion, size and minordetails' of construction within the scope of the claims may be resortedto without departure from the spirit or sacrificing any of theadvantages of the invention.

Similar characters of reference denote like or corresponding parts"throughout the sev# eral igures of the accompanying drawings,

Fig. 6 is a vertical longitudinal section of i the end portion shown inFig. 4.

Fie. 7 is a detached side view of the ad' justale clip shown in Figs.r1, 2, 3 and 8, for lockingthe removable end portion of the Fig. 8.showsa detached side view of the removable cover portion of the grease gun,the intermediate tubular portion of which has been omitted, which issomewhat preferable tor handling oils.

Fig. 9 shows an attached cross sectional view ot the adjustable Vnippleshown in Referring now in detail to the reference characters shownv uponthe drawings 10 denotes the cylindrical body, the forward end portion 11of which is rounded and provided with a slot 12 through which theadjustable nipple 13 is operatively fitted. rlhe upper end portion ofthis cylindrical reservoir is inclosed by the tubular cover la which isprovided With an internal tubular eXtension 15 that lits. into thecylindrical body and is also provided with a iange 16 that covers theouter portion of the cylinder ad'- j-acent to the said open end portion.rllhe piston rod 17 which is provided with an operating handle 18 isslidably mounted in this lncloslng cover and upon the inner end of therod is mounted the plunger 19 adapted to be drawn back and forth by therod and handle. From this constructlon apin 2O that fits into aslot 21,whenthe parts are closed together, and it is` further engaged by it willbev seen that the two cylindrical portions of the' the outer cylindricalrec the slot 22 of the adjustable sheet metal collar 23 mounted upon theouter surface of the :flange 16 and held against sidewise movementbv thelugs 2 4 formed upon the liange.

larly adjusted for the purpose of lengaging and disengaging the pin 2Oto lock the parts together, thereby releasing the same for removal andreiilling.

eferring again to the forward end of the gun it will be noted that Iprovide'a flexible .105 .This collar is obviouslyadapted to be annul theouter threaded washer 25 inside of the rounded end portion of the barrelhaving opposite sides between shoulders 30 formed by it and the flangeof the adjustable nipple 13. rlhe inner head portion of this nipple iselongated having opposite flattened sides 31 which are guided betweenthe shoulders 30 formed by the contracted or flattened sides 26S- 26 ofthis end portion of the body, leaving the outwardly extended end portionof the nipple free to be moved backward and forward within the slot 12.this nipple to allow the 'grease to be properly forced out therefrom. Anut 27 is fitted upon portion of the nipple to rmly draw the inner headportion up against the bushing of the cylinder to form a tightlconnection.

28 refers to a coupling that is detachably mounted upon the said nippleand 29 is a pipe which may be any suitable length to form a furtherextension as may be required.

As before suggested the gun isadapted to be used both as a grease gunAand an oil gun and when used for the handling of grease the gun isloaded by removing the cover and filling the gun from that end. On theother hand if it is to be used as an oiler the nozzle is .simplysubmerged in the oil and the plunger drawn back so as to suck the oil upinto the gun in the usual and Well known manner.

Having thus described my invention, what l claim and desire to secure byLetters Patent is,

1. In a grease gun of the class described, the combination of acylindrical body having an integral rounded end portion, the twoopposite. sides of which are flattened forming shoulders and providedwith a slot between the said shoulders, an adjustable nipple positionedin the slot including a threaded por- A central hole is providedthroughV tion and an integral head, the two sides' of which areflattened and positioned against the shoulders to prevent turning, theengaging face of said head being rounded to conform to the shape of theinner wall of the end of the cylindrical body, a flexible washer fittedbetween the rounded portion of the head of the nipple and the inner wallof the end of the body, a nut mounted upon the outer threaded portion of'the nipple and fitted against the end of the body, and a plungermounted Vin the cylindrical body and adapted to force the contents ofthe cylinder out through the nipple.

2. ln a grease gun of the class described, the combination of acylindrical body having one open end and an integral rounded end portionwhose two opposite sides are flat-tened to form shoulders and a slotbetween the said shoulders, an adjustable nipple positioned in the slotincluding a threaded portion and an integral elongated head withopposite atte'ned side portions positioned against the shoulders toprevent turning, and having a rounded engaging face to conform to theshape of the inner wall of the end of the body, a nut mounted upon theouter threaded portion of the nipple and fitted against the end of thebody, securing the covery to the body, and a piston and plunger mountedin the cover and cylindrical body and adapted to force the contents ofthe cylinder out through the nipple.
